A combination of high temperature and salt deposit causes a quartz torch to devitrify. Higher concentrations of salt in the samples lead to more rapid devitrification. The quartz torch in the photo was run for only 6 hours with samples containing 10% NaCl and is already badly degraded.

By contrast, the ceramic material does not devitrify and is not affected by salt deposits. The ceramic D-Torch in the photo was run for the same period and with the same samples as the quartz torch but shows no degradation at all.

The quartz outer on the D-Torch lasts much longer than the OEM model, but a ceramic is still definitely worth it. The ceramic has been great for the iCAPís that we purchased from you and will probably get another for our other iCAP too. (In reference to the D-Torch with ceramic outer tube)

The D-torch is working great! Iím very pleased with it and will let the other ICP users know about it.

We have worked with your ceramic D-Torch since three weeks and the results and the sensitivity are so far very well and I would therefore recommend that torch to other users of ICP-OES.

Our fully ceramic D-torch is in place since august 2013 and it seems to be in good shape, no major sign of deterioration.

(In reference to the D-Torch with ceramic outer tube) It works like a champ, and the base line on my Si has never been as clean as this.

We have been using the D-Torch on our Perkin Elmer ICP for about a year, and have had great success with it. We definitely see lower costs, and better Si stability.

The D torch is good value.

(In reference to the D-Torch) The torch has been excellent. We have been using it for 2 months so far and very little to no carbon buildup. Have only had to dismantle once during this time.

We have also been running with a full ceramic torch on all of our instruments for over a year now and have found them to be very reliable.

(The D-Torch) performs really well and we have had no problems with it. It performs just as well if not better than the single piece torches and obviously saves a lot of money in replacement parts.

The torch has been running like a Swiss watch ... The ceramic torch has shown no signs of deterioration, with 80 hrs/week running. The intensities on the 7300DV have also been elevated between 10-20%.

The Ceramic torch is quite excellent, mostly from a maintenance standpoint, it forms much less deposits on it and that which forms is usually very easy to clean ... I do think we'll continue buying ceramic torches mostly because they last much longer and are so much easier to keep clean.

I am quite pleased with the D-Torch. It's stable and rather easy to maintain and clean. ...Another upside is the D-torch is also much easier to push in and take out of the torch block, quartz torch tends to get stuck in the o-rings and require quite a lot of force to pull out, but the D-torch is much smoother. It's also quite excellent for analyzing silica in a hydrofluoric digestion, I noticed my blanks for that were much lower and stable.

The D-Torch is performing very well. The ceramic outer has been in almost constant service 22 hours a day, 6 days a week since we purchased it and we have had no issues...We are due to purchase a replacement ICP and will certainly be purchasing another D-Torch to go along with it.
